I have Node-RED running on a Raspberry Pi 3 at home. I have some flows in which data coming in via MQTT (the broker is on the same Raspberry Pi) is sent on to Thingspeak and to an InfluxDB database.
A strange phenomenon has popped up recently, not sure if it is actually a Node-RED thing or a general Raspberry Pi filesystem thing.
I find that if the Pi is restarted (e.g. after a power failure or shutdown), on restart, Node-RED seems to have "lost" some of my most recent flows (i.e. the parts of flows I've most recently added). I can manually put them back in and Deploy and everything works well, but the next time there is a power failure or shutdown, they're gone again.
Anyone have an idea of what the origin of this might be?
